This paper introduces a novel visualization method for proper-time in special relativity using light clocks, making space-time intervals easier to understand and emphasizing the observer-centric nature of time measurement.

Contribution

It presents a new pedagogical visualization technique that simplifies understanding of proper-time and space-time intervals in special relativity.

Findings

Enhanced understanding of proper-time through visual diagrams

Simplification of space-time interval measurement

Pedagogical tool emphasizing observer-based time measurement

Abstract

We present a new visualization of the proper-time elapsed along an observer's worldline. By supplementing worldlines with light clocks, the measurement of space-time intervals is reduced to the "counting of ticks." The resulting space-time diagrams are pedagogically attractive because they emphasize the relativistic view that "time is what is measured by an observer's clock."
